The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"corot-25","name":"CoRoT-25","class":"f9_yellow_white_star","category":"star","object_type":"F9 yellow-white star","mag":14.79,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":3599.0703968287203,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":280.6296561,"dec_deg":6.5138223,"epoch_ra_deg":280.956786,"epoch_dec_deg":6.539532,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Ophiuchus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/corot-25","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"18425+0631","companions":[{"measured":2015,"magnitude":19.2,"components":"AB","discoverer_code":"CRT  25","separation_arcsec":5.4,"position_angle_deg":42},{"measured":2015,"magnitude":20.6,"components":"AC","discoverer_code":"CRT  25","separation_arcsec":6.2,"position_angle_deg":66},{"measured":2015,"magnitude":20.5,"components":"AD","discoverer_code":"CRT  25","separation_arcsec":9.5,"position_angle_deg":350},{"measured":2015,"magnitude":19.4,"components":"AE","discoverer_code":"CRT  25","separation_arcsec":11.3,"position_angle_deg":259},{"measured":2015,"magnitude":18,"components":"AF","discoverer_code":"CRT  25","separation_arcsec":12.8,"position_angle_deg":141},{"measured":2015,"magnitude":19.5,"components":"AG","discoverer_code":"CRT  25","separation_arcsec":13.6,"position_angle_deg":75},{"measured":2015,"magnitude":18.9,"components":"AH","discoverer_code":"CRT  25","separation_arcsec":13.7,"position_angle_deg":109},{"measured":2015,"magnitude":19.8,"components":"AI","discoverer_code":"CRT  25","separation_arcsec":14.1,"position_angle_deg":39},{"measured":2015,"magnitude":16.5,"components":"AJ","discoverer_code":"CRT  25","separation_arcsec":14.1,"position_angle_deg":18},{"measured":2015,"magnitude":18.9,"components":"AK","discoverer_code":"CRT  25","separation_arcsec":15.4,"position_angle_deg":217},{"measured":2014,"magnitude":19.4,"components":"AL","discoverer_code":"CRT  25","separation_arcsec":15.7,"position_angle_deg":214},{"measured":2015,"magnitude":19.8,"components":"AM","discoverer_code":"CRT  25","separation_arcsec":15.9,"position_angle_deg":154},{"measured":2015,"magnitude":19.7,"components":"AN","discoverer_code":"CRT  25","separation_arcsec":16,"position_angle_deg":161},{"measured":2015,"magnitude":19.1,"components":"AO","discoverer_code":"CRT  25","separation_arcsec":17.2,"position_angle_deg":35},{"measured":2015,"magnitude":19.5,"components":"AP","discoverer_code":"CRT  25","separation_arcsec":17.2,"position_angle_deg":54},{"measured":2015,"magnitude":18.2,"components":"AQ","discoverer_code":"CRT  25","separation_arcsec":17.5,"position_angle_deg":142},{"measured":2015,"magnitude":19.7,"components":"AR","discoverer_code":"CRT  25","separation_arcsec":18,"position_angle_deg":129},{"measured":2015,"magnitude":19.6,"components":"AS","discoverer_code":"CRT  25","separation_arcsec":18.3,"position_angle_deg":187},{"measured":2015,"magnitude":18.9,"components":"AT","discoverer_code":"CRT  25","separation_arcsec":18.8,"position_angle_deg":245},{"measured":2015,"magnitude":18.8,"components":"AV","discoverer_code":"CRT  25","separation_arcsec":18.9,"position_angle_deg":202},{"measured":2015,"magnitude":16.3,"components":"AU","discoverer_code":"CRT  25","separation_arcsec":19.1,"position_angle_deg":227}],"mass_solar":1.09,"radius_solar":1.19,"spectral_type":"F9","uncertainties":{"metallicity_fe_h":[0.03,0.03]},"stars_in_system":1,"metallicity_fe_h":0.16,"planets_in_system":1,"surface_gravity_log_g":4.41,"surface_temperature_k":6040,"metallicity_fe_h_source":"One spectroscopic determination, compiled from the literature (PASTEL, Soubiran+ 2016)","stellar_parameters_method":"NASA Exoplanet Archive composite parameters"},"designations":[],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
